A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT AbstractDeep eutectic solvents are evaluated as media for the electropolymerisation of 3,4-ethylenedioxythiophene (EDOT) for the first time. PEDOT modified glassy carbon electrodes (GCE) were characterised by cyclic voltammetry, electrochemical impedance spectroscopy and scanning electron microscopy. PEDOT modified GCEs prepared from choline chloride-urea (reline) and choline chloride -ethylene glycol (ethaline) exhibited interesting electrocatalytic and morphological characteristics. Fixed potential sensing of ascorbate at 0.0 V showed a greater electrocatalytic effect, significantly higher sensitivity and lower detection limit than at hitherto reported PEDOT modified electrodes.

An effective approach to enhanced thermoelectric properties of PEDOT:PSS films by a DES post-treatment

“…Even so, we note that at present there are still relatively few reports about the simultaneous increases in electrical conductivity and Seebeck coefficient. Deep eutectic solvents (DES) as a new generation of green solvents with advantages of low price, chemical inertness with water (i.e., easy storage), easy preparation, biodegradability, biocompatibility and nontoxicity, have been successfully applied in the preparation of functional materials as media including the electropolymerization of TE materials such as EDOT, aniline, and so forth . However, more direct influence of DES on the properties of thermoelectric materials is not found yet.…”

Corrosion Processes of Uranus B6 and Monel 400 Special Alloys in Deep Eutectic Solvents

“…Generally, DESs are perepared as a mixture composed of a quaternary ammonium salt and a hydrogen bond donor. The melting point of the DESs is lower than their individual components, this decrement being a consequence of the hydrogen bond between halide ion and hydrogen bond donor [5][6][7].…”

Ultrasound‐Assisted Natural Deep Eutectic Solvents as Separation‐Free Extraction Media for Hydroxytyrosol from Olives

“…[2] In the case of DESs, the interaction between hydrogen bonds and anions indirectly increases the size of the anions themselves, thereby reducing the interactions between anions and cations, ultimately leading to a decrease in the melting point of the eutectic phase. To date, DESs have been applied extensively in the fields of organic synthesis, electrochemistry [5][6][7][8] , polymer synthesis [5,9,10] , superconductors, biological sensors, medical health [13][14][15] , CO 2 capture [16] , extractive desulfurization [17] and volatile fatty acid removal [18] . Importantly, DESs are non-volatile, safe, recyclable, and environmentally friendly.…”
